Consensus Protocol

Definition ∞ A consensus protocol is a set of rules and procedures that distributed network participants follow to agree on the validity of transactions and the state of the ledger. It ensures that all nodes in a blockchain network maintain an identical and accurate record of transactions. These protocols are foundational to the security and trustworthiness of any distributed ledger technology.
Context ∞ The current dialogue concerning consensus protocols is largely focused on the scalability and energy efficiency trade-offs between different mechanisms, such as Proof-of-Work and Proof-of-Stake. Debates often highlight the security guarantees and decentralization properties of various approaches. Future developments are expected to center on the implementation of novel consensus algorithms that aim to achieve higher throughput while maintaining robust security and decentralization.
